INTRODUCTION
This Traffic Signal Warrant Analysis has been prepared at the
request of the Department of Community Development, City of Carmel.
The traffic signal warrant analysis is for the intersection of
116th Street and the Keystone Square Shopping Center Driveway in
Carmel, Indiana.
PURPOSE
The purpose of this analysis is to determine if the existing
traffic volumes will be sufficient to warrant the installation of
a traffic signal at the intersection of 116th Street and Keystone
Square Shopping Center Driveway.
SCOPE OF WORK
The scope of work for this analysis is to first determine the
existing traffic volumes at the intersection of 116th Street and
Keystone Square Shopping Center Driveway.
Based on the data that has been developed, prepare a traffic signal
warrant analysis for the intersection of 116th Street and Keystone
Square Shopping Center Driveway.
TRAFFIC DATA
A & F Engineering Co. , Inc has made a 12-hour manual traffic
volume count at the intersection. This traffic volume count
includes a hourly total of all traffic as it approaches the
1
intersection. This traffic volume count was made on December 7,
1994 . A summary of the hour by hour traffic volumes between the
hours of 8 : 00 AM to 8:00 PM is shown in Table 1. A copy of the
total traffic volume count is included in Appendix A.
